I saw the Season 2 premiere of Joss Whedon's Dollhouse and it's starting off with a bang.  Dollhouse took a while to get going, but I think it's one of the most intriguing and intelligent shows on TV.  As an added bonus to Battlestar Galactica fans, the season 2 premiere guest starred Jamie Bamber (Lee Adama).

If you're new to Dollhouse, it's essential to start with Season 1.  Keep in mind that the first 5 episodes are moderately interesting, but the show starts to pick up quickly after that.
